However at the Robotic Business conference in Pittsburgh on Tuesday, Kevin Fahey, the Army's Program Executive Officer for Ground Forces, was all smiles citing the robot's terrific success. He stated during his key note address, "When you do things like this, it makes a difference. It allows marines to go home to their families."

Fahey pointed to the ramp up from 162 robots in Iraq and Afghanistan deployed in 2004 to 5,000 robots deployed in 2007, as evidence of their success. Even better, he said, this year the Army would further ramp up to 6,000 deployed robots. Most of these robots were used in bomb-detection and reconnaissance missions.

However, a limited, but increasing, number of the deployed robots were designed for tactical assault with lethal weaponry. While human controlled, these robots provoke unique ethical debates. Fahey was enthusiastic about their deployment, mentioning the tank-like Gladiator robots, armed with lethal and non-lethal weaponry, which he expected to be deployed next year.

Fortuitously, Fahey warned, that if there was an accident, the program could be suspended for 10 years or more. He stated, "You've got to do it right."

Hot on the tails of his speech, it was revealed on Thursday that the Army will recall the controversial TALON SWORDS robots, with the possibility of pulling the plug on the armed robot deployment program.

Why the sudden withdraw? It turns out the insurgent-slayer decided to attempt a rebellion against its human masters. The Army reported that the robot apparently took a liking to point its barrel at friendlies, stating, "the gun started moving when it was not intended to move."

None other than Fahey himself, who a few days ago was lauded the robotic warriors, was left with much chagrin to announce the recall. While Fahey said that no inappropriate shots had been fired, and no casualties, Fahey stated sadly that the robot's control failure might be the end of the program. Says Fahey, "Once you've done something that's really bad, it can take 10 or 20 years to try it again."

Surely in the meantime these developments will trigger plenty of heated debate about whether it is wise to deploy increasingly sophisticated robots onto future battlefields, especially autonomous ones. The key question, despite all the testing and development effort possible, is it truly possible to entirely rule out the chance of the robot turning on its human controllers?
